VRE310
The proper connection of the VRE310 series voltage references with the optional trim resistor is shown below. The
VRE310 reference has the ground terminal brought out on two pins (pin 4 and pin 7) which are connected together
internally. This allows the user to achieve greater accuracy when using a socket. Voltage references have a volt-
age drop across their power supply ground pin due to quiescent current flowing through the contact resistance. If
the contact resistance was constant with time and temperature, this voltage drop could be trimmed out. When the
reference is plugged into a socket, this source of error can be as high as 20 ppm. By connecting pin 4 to the power
supply ground and pin 7 to a high impedance ground point in the measurement circuit, the error due to the contact
resistance can be eliminated. If the unit is soldered into place, the contact resistance is sufficiently small that it does
not effect performance. Pay careful attention to the circuit layout to avoid noise pickup and voltage drops in the lines.
